Word timestamps first
Word-by-word highlighting needs word-level timestamps. Run alignment first if your transcript does not have them yet.
Put it on the video
An ASS file works in players and editors that support it. To burn it into the picture with ffmpeg (installed separately):
ffmpeg -i video.mp4 -vf "ass=karaoke.ass" -c:a copy out.mp4
Speaker names when you need them
Karaoke subtitles can prefix speaker names, which helps with interviews and panels.
